Description

Challenger MT735 MT745 MT755 MT765 MT745B MT755B MT765B Track Tractor Service Manual

This is the complete service manual set published by AGCO for the Challenger MT700 and MT700B Series rubber track tractors. It covers MT735, MT745, MT755, MT765, MT745B, MT755B and MT765B models in both CE and Non-CE configurations. Document number 79023971 C Rev., dated October 2005.

This manual is built for professional technicians and serious owner-operators who need real procedures, real specifications and real diagnostic flows, not just a general overview. Every section is drawn from the same documentation AGCO service departments use when these tractors come in for repair.

Chapters Covered

The manual is organized into divisions, each with its own identifying part number, revision level, table of contents, safety section and index. The main divisions are:

• 01A — Introduction
• 02A — Engine
• 02B — Engine Auxiliary Components
• 03A — Powertrain Systems Operation, Testing and Adjusting
• 03B — Powertrain Disassembly and Assembly
• 04A — Steering and Brake System
• 05A — Undercarriage System
• 06A — Hydraulic and Three-Point Hitch Testing and Adjusting
• 06B — Hydraulic Schematics
• 07A — Electrical Schematics
• 08A — Tractor Management System Center (TMC)
• 08B — Auto-Guide Systems Operation
• 09A — Cab Heating and Air Conditioning
• 10A — Component Specifications
• 10B — Component Disassembly and Assembly
• 11A — Troubleshooting

Under each division you get everything from the diagnostic code library (MID 039, MID 053, MID 078, MID 082 and MID 123) and transmission clutch engagement charts to hydraulic schematic pages and electrical schematic page sets. The Powertrain division alone breaks down the Caterpillar power shift transmission into component-level removal, disassembly, assembly and install steps for the steering pump, steering motor, brake valve assembly, tandem charge pump, hydraulic pump, control valves, three-point hitch, drawbar and more. The Undercarriage division handles the Mobil-trac belt system, tensioner, idler hub, bogie assembly, drive wheel support and gauge spacing.

What this gives a technician is end-to-end coverage. You can diagnose a fault through the TMC or with a laptop and Caterpillar Electronic Technician, follow the diagnostic code table to the exact test procedure, then pull the component, disassemble, inspect against the specification tables, reassemble, install, calibrate and test. Every one of those steps is documented here. The Auto-Guide and TMC sections walk through configuration, calibration and troubleshooting of the precision farming and guidance systems, which are notorious for stumping people who only have the operator manual.

What You Can Do With This Manual

• Run complete engine service and auxiliary removal/reinstall procedures
• Diagnose and repair the Caterpillar power shift transmission at component level
• Service the steering differential, service brakes, parking brake and trailer brake systems
• Rebuild the undercarriage — belts, idlers, midwheels, drive wheel, tensioner and bogie
• Test and adjust the implement hydraulic system, three-point hitch and steerable hitch
• Read and interpret hydraulic schematics and complete electrical schematics
• Configure, calibrate and troubleshoot the Tractor Management Center (TMC)
• Operate, configure and diagnose the Auto-Guide satellite navigation system
• Service the cab HVAC system, refrigerant circuit, blower, evaporator and heater core
• Work through every MID/CID/FMI diagnostic code with the correct test procedures
• Look up torque values, capacities, tolerances and component specifications

Why This Manual Matters

The Challenger MT700 Series tractors are complex machines. They combine a Caterpillar diesel engine, a Caterpillar 16F/4R power shift transmission, an electronically-controlled steering differential, a fully hydraulic three-point hitch, a hydraulic brake system with accumulator, an Auto-Guide satellite guidance system and a Tractor Management Center that ties it all together over CAT and CAN data links. Getting a repair wrong on this equipment is expensive. Getting calibration wrong on the steering or transmission can damage the machine or create a safety hazard.

Having the actual service manual means you can match the exact procedure, the exact torque, the exact pressure and the exact calibration steps. No guessing, no borrowed settings from a different model, no wasted parts.
